Sofar I've noticed that the two alter ego characters we have gotten out of the Hulk set are worded differently than previously. "Give X a power action that deals no pushing damage and replace this character with X"

Has this just started? Or has it been like this for awhile and I have just completely looked over it? It makes AE much more attractive to play, a little less strategic imo but much better.

I believe that Green Lantern and Hal Jordan from the gravity feed had the no pushing damage. But all the Hulk Alter Egos show have had "This power can't be countered." and that is new.

And to be clear, each of the different mechanics are specific to their character. Just because Matt Murdock's Alter Ego power cannot be countered does not provide any protection for Clark Kent.

when did we see matt murdocks dial and card?

It has not been previewed... But some people might have an "in" to seeing such abilities and previews... But I don't want to make speculations.
